You can attack the Wild Bunch Gang (NPC) by clicking on the map or other players via the button next to the map.
On the map, choose the county which is green and choose one area occupied by the Wild Bunch Gang. Click on the “Start attack” button to get to the menu of fighting arrangements.
Your available positions are the red ones. On every spot you can position one of your units, choosing the particular type of units first. If you would like to use more than one unit type, make sure that you do not place all your units on one spot when starting to arrange the fight.
As soon as your line-up is ready, click “fight” to start the battle.
